We used their Excel Plug-in to input twitter data which worked really well.
We were also looking for the sentiment of our content. Our business problem was to calculate sentiment score and do graph analysis. Semanntria did that very well.,assign sentiment score

If you are a basic license user, semantria does well and presents analysis quickly. After the analysis, it creates multiple tabs with different views of the data and some visualizations and graph analysis also. The graph analysis and node connector graph is very useful. Their algorithm is very strong and it gives correct sentiment score even for neutral statements. I didnt get to use the API version of semantria so have no comments about that. Upon reading online about it, i found that the integration takes a while .
